Network: 5G network availability may vary depending on the country, network provider and user environment. The difference is notable between Samsung’s obvious competition, too: on the standard iPhone 12, you get wide and ultra-wide, while the Samsung S21 offers wide, ultra-wide, and close. It’s that sort of difference which could just win people over to what Samsung offers, provided the quality is there.

Specification
The S21 line comprises four models with various hardware specifications. International and Korea models of the S21 utilize the Exynos 2100 SoC, while the U.S., Canadian, Chinese, Taiwanese, Hong Kong and Japanese models utilize the Qualcomm Snapdragon 888. [13] The U.S., Canadian, Chinese, and international (European) models of the S21 FE use the Snapdragon 888, while Korean, Indian, Brazilian and Australian markets use Exynos 2100. Information about the dimensions of the image sensor used in the device. Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution.

The One UI 5 update based on Android 13 began rolling out to S21 devices on 7 November 2022. [32] Reception [ edit ] Crop factor is the ratio of the dimensions of a full frame camera's sensor (36 x 24 mm, which equals the frame size of a 35 mm film) and the dimensions of the image sensor of the device. The number shown is the ratio between the diagonals of a full frame sensor (43.3 mm) and the sensor in question.
That’s not a brilliant outcome for a new chip, and makes us wonder about the chip and its performance, and what the Exynos is doing to other parts of the phone. Plus there’s the knowledge that the American model may perform better, given it has a totally different chip with similar features, the Qualcomm Snapdragon 888. That hits the value hard, because while the Galaxy S21 is a high-priced phone, and the spec list certainly helps it get there, it still feels a little exy for the overall delivery.

How about these alternatives?
Given the comparison, the value isn’t far off the competition — which is good — even if the result doesn’t feel as balanced — which less positive. From left to right: Apple iPhone 12, Samsung Galaxy S21, Samsung Galaxy S20+ What needs work?
And you know what? The quality isn’t bad at all, with Samsung making some changes to how the sensor works, improving the results, while also fixing the interface and moving beyond its rather silly interpretation of portrait mode called “Live Focus”, which thankfully has been moved out of the Galaxy range. The Galaxy S21 and S21 Plus do at least one thing better than the Ultra". Android Authority. 19 January 2021 . Retrieved 19 January 2021. Battery: Actual battery life varies by network environment, features and apps used, frequency of calls and messages, number of times charged, and many other factors. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
